Waterproof housing for mobile electronic device and waterproof adapter for accessory device

ABSTRACT

A waterproof adapter can provide a liquid-tight seal between a waterproof housing for a mobile electronic device and an accessory connector extending from an accessory device, such as a jack plug extending from a pair of headphones. The waterproof adapter can be an integral part of the accessory connector or can be installed on the accessory connector using, for example, a threaded or bayonet-style connection. In one example, the waterproof adapter can include an exterior gasket channel circumscribing an exterior surface of its body, an exterior gasket disposed at least partially within the exterior gasket channel, thereby permitting the waterproof adapter to provide a liquid-tight seal between a connector aperture in the waterproof housing and the accessory connector. When the accessory device is disconnected from the mobile electronic device, a port-sealing bung can be inserted into the connector aperture of the waterproof housing and can provide a liquid-tight seal therewith.

This application claims the benefit of U.S. Provisional Patent Application No. 61/869,622 filed on Aug. 23, 2013, U.S. Provisional Patent Application No. 61/871,207 filed on Aug. 28, 2013, and U.S. Provisional Patent Application No. 61/974,399 filed on Apr. 2, 2014, each of which is incorporated by reference in its entirety as if set out fully herein.

FIELD

This disclosure relates generally to waterproof housings for mobile electronic devices and waterproof adapters for connecting accessory devices to the mobile electronic devices encased within the waterproof housings while not compromising the waterproof nature of the housings.

BACKGROUND

Mobile electronic devices, such as smartphones, portable media players, personal computers, e-readers, tablet computers, and digital audio players, are becoming increasingly important in peoples' day-to-day lives. People rely on mobile electronic devices to communicate with others, engage in commerce, listen to music, watch videos, and manage personal calendars, just to name a few. Due to the high cost of mobile electronic devices, there is a strong incentive to protect these devices from physical damage. Protective cases are readily available, but most of these cases are designed to simply protect electronic devices from drop and crush-induced damage and do not provide sufficient protection against liquid intrusion. For cases that protect against liquid intrusion, connection of a corded accessory device, such as corded headphones or fitness sensors, typically requires opening a port door on the case, which creates an opening for liquid intrusion and renders the case no longer waterproof.

SUMMARY

In one aspect, a waterproof adapter can be configured to provide a liquid-tight seal between a waterproof case for a mobile electronic device and an accessory connector of an accessory device. The waterproof adapter can include a body having an exterior surface and a hole passing through a centerline axis of the body, where the hole defines an interior surface of the body. The waterproof adapter can also include two or more tension tabs extending from a first end of the body, where each tension tab comprises a lip portion that extends outwardly relative to the axis of the body. The waterproof adapter can include an exterior gasket channel on the exterior surface of the body, where the exterior gasket channel circumscribes the exterior surface of the body. An exterior gasket can be disposed within the exterior gasket channel on the exterior surface of the body.

DETAILED DESCRIPTION

Liquids can damage sensitive electrical components within mobile devices. It is therefore desirable to develop an apparatus that prevent liquids from contacting sensitive electrical components while also not interfering with the functionality or usability of the mobile device. A wide variety of protective cases are available for mobile devices, but most fail to provide sufficient protection against liquid intrusion. Those cases that do protect against liquid intrusion typically fail to remain waterproof when a user accesses a physical feature of the electronic device. For example, if a user wants to listen to music through headphones while jogging, the user must open an access port on the case and insert a headphone plug into a headphone jack (i.e. a physical feature) of the mobile device. The access port on the case remains open while headphone plug is connected to the headphone jack in the electronic device. As a result, the case is not waterproof during this period of time, and the electronic device is susceptible to liquid intrusion from, for example, rain while the user is jogging. To avoid this outcome, it is desirable to develop an apparatus that enables the case to remain waterproof even when the user is accessing certain physical features of the electronic device, such as a headphone jack or other electrical connector, when the electronic device is housed within the case.

A waterproof or water-resistant housing 60, as shown in FIGS. 8A-B, can be configured to encase and protect a mobile electronic device 70 from liquid intrusion. The housing 60 can include an aperture 40 that allows a user to access a feature (e.g. jack, switch, fingerprint scanner, or touchscreen) associated with the mobile electronic device 70 while the device remains encased in and protected by the housing. Through the aperture 40 in the housing 60, the user can connect an accessory device (e.g. headphones, microphone, speaker, battery charger, external data storage device, auxiliary antenna, global positioning system (GPS), heart rate sensor, cadence sensor, etc.) to a jack 72 (e.g. female connector) in the mobile electronic device (see, e.g. FIG. 8B). In certain instances, a liquid-tight seal can be formed by coupling an accessory connector (e.g. the accessory connector 9 shown in FIGS. 1 and 7) associated with the accessory device to the housing 60. In other instances, a liquid-tight seal can be formed by inserting a port-sealing bung (e.g. the port-sealing bung 25 shown in FIG. 2 or 5) into the aperture 40.

As illustrated in FIG. 1, an accessory device, such as those mentioned above, can include an accessory connector 9 that permits the accessory device to be electrically connected to the mobile electronic device 70. In one example, the accessory connector 9 can include a jack plug 10 extending from a body 13. The body 13 of the accessory connector can include one or more grasping features (e.g. ridges, knurls, depressions, rubber coating, etc.) that permit a user to easily grasp the accessory connector with their fingers during insertion and removal of the accessory connector. The accessory connector 9 can also include a threaded feature 12 and a jack plug gasket 11. The jack plug gasket 11 can be an O-ring or other suitable sealing component. The accessory connector 9, by way of the threaded feature 12 and jack plug gasket 11, can be configured to provide a liquid-tight seal between the accessory connector and a connector aperture 40 in the housing 60 (see, e.g., FIG. 2), thereby preventing water from entering an interior volume of the housing and damaging sensitive components within the mobile electronic device stored therein.

In some examples, the accessory connector 9 can include a threaded feature 12 (see, e.g., FIG. 1) to permit the accessory connector to removably engage the housing 60, and in other examples, the accessory connector 9 can include cam feature (see, e.g., FIG. 3) to permit the accessory connector to removably engage the housing 60. Where the accessory connector 9 includes a threaded feature 12 or cam feature (such as a bayonet-style locking mechanism), a corresponding threaded feature or cam feature can be included in the connector aperture 40 of the housing 60 (see, e.g., FIGS. 4A, 4B, and 5). The cam feature shown in FIG. 3 can allow the accessory connector 9 to quickly and easily engage the housing 1, thereby providing greater ease of use than a threaded connection.

The jack plug 10 of the accessory connector 9 can include an electronic device interface. In some embodiments, as shown in FIG. 1, the jack plug 10 can be configured to transmit electrical signals, such as audio signals. In some embodiments, the jack plug 10 can include a headphone connector, such as a TS, TRS, or TRRS connector. In some embodiments, the jack plug 10 may be configured to transmit optical signals and may include an EIAJ optical connection (e.g., TOSLINK). In some embodiments, the jack plug 10 may be configured to transmit a combination of electrical and optical data signals. The accessory connector 9 can be configured to pass through a connector aperture 40 of a housing 60 so as to associate with an encased electronic device 70, and also to associate with one or more features within the connector aperture 40 of the housing 60 in such a manner as to establish a liquid-tight seal therewith. In this instance, the accessory connector 9 can include an attachment mechanism that includes a threaded feature 12. In other embodiments, the attachment mechanism can be a bayonet-style mounting mechanism as shown in FIGS. 3 and 4.

FIG. 1 provides a perspective view of a portion of an accessory connector 9 for an accessory device, such as a set of headphones. The accessory connector 9 can include a jack plug 10 and a jack plug gasket 11 installed on or affixed to the jack plug. The accessory connector 9 can be configured to provide a liquid-tight seal between the accessory connector and a connector aperture 40 of a housing 60 for a mobile electronic device. The jack plug gasket 11 can be located against a gasket seating surface associated with the body 13 of the accessory connector 9. The accessory connector 9 can include a threaded feature 12 located between the jack plug 10 and the jack plug gasket 11. The accessory connector 9 can be configured to pass through the connector aperture 40 of the housing 60 so as to associate with an electronic device removably encased within the housing. The accessory connector 9 can be configured to associate with the connector aperture 40 of the housing 60 in such a manner as to establish a liquid-tight seal therewith. In this instance, the accessory connector 9 includes a threaded feature 12, which is configured to interface with a corresponding threaded feature of the connector aperture 40.

FIG. 2 provides a side cutaway view of a threaded connector aperture 40 into which a threaded port-sealing bung 25 or threaded accessory connector 9 (see FIG. 1) may be threaded. In FIG. 2, the threaded port-sealing bung 25 is installed in the connector aperture 40 to prevent entry of liquids, dust, or debris into the housing 60 when an accessory device 9 is not occupying the connector aperture 40. For example, if a user has disconnected her headphones from the mobile electronic device, the user can install the threaded port-sealing bung 25 into the connector aperture 40 to prevent entry of liquids, dust, or debris into the housing 60. The port sealing bung 25 can include a bung gasket 36 which enhances the liquid-tight seal.

In order for the jack plug 10 of the accessory connector 9 shown in FIG. 1 to be inserted into the connector aperture 40 of the housing 60 of FIG. 2, the port-sealing bung 25 is unscrewed from the connector aperture 40. The threaded feature 12 of the accessory connector 9 can then be screwed into a corresponding threaded feature of the connector aperture 40. To avoid losing or misplacing the port-sealing bung 25 while it is removed from the connector aperture 40, the port-sealing bung 25 can include a tether that attaches to the housing 1, similar to the tether 910 shown in FIG. 9.

FIG. 3 provides a side view of an embodiment of an accessory connector 9 with a jack plug 30 and a bayonet-style mounting feature 32. The accessory connector 9 can include a jack plug gasket 31 that can be any suitable removable gasket (e.g. an O-ring) or non-removable gasket (e.g. a formed-in-place gasket associated with a body of the accessory connector). The accessory connector 9 can include one or more cam features 33 a-d (33 d not visible in FIG. 3) extending radially from the accessory connector. In some embodiments, one, two, three, four, five, or more cam features may extend radially from the accessory connector 9. Where the accessory connector includes cam features, such as 33 a-d, corresponding cam receiving features 43 a-d can be included in the connector aperture 40 of the housing, as shown in FIGS. 4A and 4B. The jack plug 30 of the accessory connector shown in FIG. 3 is configured to pass through the connector aperture 40 of the encasement or housing so as to associate with a jack in an encased electronic device. As shown in FIG. 3, the accessory connector can include cam features 33 a-d that are adapted to engage corresponding cam receiving features 43 a-b (see FIGS. 4A and 4B) of the connector aperture 40 of the housing 60 so as to establish a liquid-tight seal with the aid of the jack plug gasket 31.

FIG. 4A provides a close-up perspective view of a portion of a housing 60 with a connector aperture 40 having bayonet-style mounting features disposed within the connector aperture. The connector aperture 40 can include cam receiving features (e.g. 43 a, 43 b) disposed within the wall of the connector aperture. The connector aperture 40 can be adapted to receive either a bung (see, e.g., port-sealing bung 35 shown in FIG. 5) or an accessory connector (see, e.g., accessory connector shown in FIG. 3) with bayonet-style mounting features (e.g. 33 a-d).

FIG. 4B depicts a cutaway view of a connector aperture 40 with bayonet-style mounting features 43 a and 43 b and disposed within the wall of the connector aperture. In some embodiments, the connector aperture 40 includes only a bayonet-style mounting feature and not a threaded feature, as shown in FIG. 4A. When a port-sealing bung 35 or accessory connector 9 is received within the connector aperture 40, a liquid-tight seal is established due to compression of a gasket (e.g. 26) against a gasket seating surface, as shown in FIG. 5.

FIG. 5 provides a side cutaway view of a housing 60 with a connector aperture 40 having a bayonet-style mounting feature with a port-sealing bung 35 installed in the connector aperture 40. When the port-sealing bung 35 is installed into the connector aperture 40, the gasket 26 is compressed between a first gasket seating surface located on the bung and a second gasket seating surface located within the connector aperture, thereby forming a liquid-tight seal between the bung and the housing 1.

Another configuration of a waterproof linkage for a data connector includes a linkage that is pressed directly into a receiving feature or port of an encasement or housing without requiring rotation to facilitate coupling (in contrast to the threaded connection shown in FIG. 2 or the bayonet style connection of FIG. 5). The waterproof adapter described herein can be molded directly to the accessory connector 9, or it can be configured as a separate waterproof adapter component (see, e.g. FIGS. 6A-6C) that includes threads, cam features, or other attachment features that allow the adapter to be attached to or installed on the accessory connector in a waterproof manner (see, e.g. FIG. 7B).

In certain instances, it can be desirable to have a quick-connect feature that allows the accessory connector 9 to form a liquid-tight seal against the housing 60 without having to thread or twist the accessory connector into the connector aperture 40, thereby simplifying installation for a user. For instance, it can be desirable to have a quick-connect feature that allows the accessory connector 9 to be pressed into the connector aperture 40 with a single motion, thereby simplifying and speeding the connection process and reducing the likelihood of a partial installation. To achieve this outcome, the connector aperture 40 can be configured to receive a waterproof adapter 50 (see FIGS. 6A-C) that attaches to the accessory connector 9, as shown in FIG. 7B. FIG. 8A shows an example of a portion of a housing having a connector aperture 40 prior to installation of the accessory connector 9 with a quick-connect feature, and FIG. 8B shows an example of a portion of a housing having a connector aperture 40 after installation of an accessory connector 9 with a quick-connect feature.

FIGS. 6A-C depict several views of a waterproof adapter 50 in the form of a threaded waterproof adapter. FIG. 6A shows a bottom perspective view of a waterproof adapter 50. In one example, the waterproof adapter 50 can have a body 59 with a hollow cylindrical or barrel shape. The waterproof adapter 50 can have an exterior gasket channel 51 located on an outer circumference of the body 59 at or near a middle region of the body. The gasket channel 51 can be configured to receive a gasket or seal 52, such as an O-ring, as shown in FIG. 8B (FIGS. 6A-6C show the waterproof adapter 50 prior to installation of the gasket of seal 52). The bottom side of the waterproof adapter 50 can include a perimeter, and the perimeter can include one, two, three, four, or more tension tabs (53 a-d) extending therefrom. In one example shown in FIG. 6A, the perimeter of the bottom side of the waterproof adapter 50 can include four tension tabs (53 a-d) extending therefrom. Each tension tab (53 a-d) can have a lip portion (54 a-d) extending outward radially (e.g. flaring outward) from the tension tab (i.e. extending outwardly from a centerline axis 100, as shown in FIGS. 6A-C and 8B). In other embodiments, the number of tension tabs may be two, three, five, or more. The lip portions (54 a-d) can project outwardly at a predefined angle from the tension tabs (53 a-d) and can be configured such that the waterproof adapter 50 may be inserted into a connector aperture 40 of the housing 60 and can be removably secured therein, as shown in the side cutaway view of FIG. 8B. The tension tabs (53 a-d) and lip portions (54 a-d) enable the waterproof adapter to function as a quick-connect style connector that is affordable and replaceable and can be sterilized (e.g. to permit use in hospital environments).

The lip portions (54 a-d) can project outwardly from the tension tabs (53 a-d) at any suitable angle. In one example shown in FIG. 6C, the lip portions (54 a-d) can project outwardly from their respective tension tabs (53 a-d) at an angle of about 45 degrees relative to the centerline axis 100 of the waterproof adapter 50. Depending on considerations relating to ease of insertion, ease of removal, and protection against inadvertent removal, the lip portions (54 a-d) can project outwardly from the tension tabs (53 a-d) at other suitable angles, such as about 1-15, 15-30, 1-60, 15-60, 15-45, or 30-45 degrees, relative to the centerline axis 100 of the waterproof adapter 50. The lip portions (54 a-d) of the tension tabs (53 a-d) can have rounded end portions, as shown in FIG. 6C, to ease insertion and removal of the waterproof adapter 50 into the connector aperture 40 of the housing 60. By having smooth, rounded end portions on the lip portions (54 a-d) of the tension tabs (53 a-d), damage (such as gouges, scratches, or other forms of wear) to inner surfaces of the connection aperture 40 can be reduced or avoided during insertion and removal of the accessory connector 9 to and from, respectively, the connector aperture. Reducing or avoiding damage, such as gouges or scratches, to the inner surface of the connector aperture 40 is desirable, since it ensures the gasket or seal 52 of the waterproof adapter 50 is not abraded during an insertion or removal step thereby promoting the gasket or seal's longevity and also ensuring the gasket or seal is placed in contact with a reliable sealing surface to form a liquid-tight seal when inserted into the connector aperture.

During insertion of the waterproof adapter 50 into the connector aperture 40, the lip portions (54 a-d) and tension tabs (53 a-d) can deflect inward (slightly) toward the centerline axis 100 of the waterproof adapter. Once inserted, the lip portions (54 a-d) can exert an outward force against an inner surface of the connector aperture 40 or, alternatively, a channel or protrusion within the connector aperture or an interior surface of the housing 60 (see FIG. 8). The outward force applied by the lip portions (54 a-d) can result from the lip portions and tension tabs (53 a-d) attempting to resume their original shapes that existed prior to being deflected inwardly as a result of insertion of the waterproof adapter 50 into the connector aperture 40. The waterproof adapter 50 can have an outer diameter that is slightly smaller than a corresponding inner diameter of the connector aperture 40 to which it mates, thereby establishing an annular gap between the outer surface of the waterproof adapter 50 and an inner wall of the connector aperture 40 upon insertion. The exterior gasket 52 (see FIG. 8B) can have an outer diameter that is larger than the inner diameter of the connector aperture 40. The exterior gasket 52 can fill the annular gap between the outer surface of the waterproof adapter 50 and the inner wall of the connector aperture 40. The exterior gasket 52 can be at least partially compressed against the inner wall of the connector aperture 40 upon insertion of the waterproof adapter 50 into the connector aperture 40, thereby creating a water-tight seal, as shown in FIG. 8B, that prevents liquid from reaching the electronic device through the connector aperture.

Returning to FIG. 6A, the waterproof adapter 50 can be hollow, thereby establishing an inner surface that can include a threaded feature 56. The threaded feature 56 can allow the waterproof adapter 50 to be threaded onto (i.e. threadably engaged with) a corresponding threaded feature 12 of the accessory connector 9. FIG. 7A shows the accessory connector 9 prior to installation of the waterproof adapter 50, and FIG. 7B shows the accessory connector 9 after installation of the waterproof adapter.

FIG. 6B depicts a bottom perspective view of the waterproof adapter 50. An interior gasket seat 55 can exist on an inner circumference of the waterproof adapter 50. The interior gasket seat 55 can be configured to press against a jack plug gasket 11 located on the accessory connector 9 when the waterproof adapter 50 is threaded onto the accessory connector. The jack plug gasket 11 provides a water-tight seal between the body 13 of the accessory connector and the waterproof adapter 50 when the waterproof adapter is threaded far enough onto the threaded portion 12 of the accessory connector 9 to sufficiently compress the jack plug gasket between body of the accessory connector and the interior gasket seat 55 of the waterproof adapter. Waterproof adapter 50 may also include a gasket, in addition to or as an alternative to jack plug gasket 11, for forming a seal between waterproof adapter 50 and accessory connector 9.

The waterproof adapter 50 can be removably installed on the accessory connector 9 or can be permanently or semi-permanently affixed to the accessory connector by any suitable process. In some embodiments, an adhesive (e.g. glue, epoxy, LOCTITE) may be applied to the threads of either threaded feature (12, 56) to secure the waterproof adapter 50 to the accessory connector 9. The waterproof adapter 50 may also be welded (e.g. ultrasonically welded) to the threaded feature 12 of the accessory connector 9. In some embodiments, the waterproof adapter 50 may not have a threaded feature to permit engagement with the accessory connector 9 and may instead be adhered, welded, bonded, or otherwise fastened to the accessory connector by any other suitable approach. In some embodiments, the waterproof adapter 50 may be overmolded onto the accessory connector 9 or may be formed as part of the accessory connector. For example, the waterproof adapter 50 can be an integrally formed portion of the accessory connector 9 created by, for example, an injection molding process wherein the body of the accessory connector and the waterproof adapter are formed as a single component. The waterproof adapter 50 can be used with either male or female connectors. For example, if a housing 60 for mobile electronic device includes a male connector, the waterproof adapter 50 may be fitted to the body of a female accessory connector 9, thereby allowing for insertion of the female connector into or through the connector aperture 40 in the housing 60 and sealing the connector aperture against liquid and/or dust intrusion. In some embodiments, a male connector associated with the housing 60 may partially enter the connector aperture 40. In some embodiments, the mobile electronic device itself may include a male connector positioned proximate a connector aperture 40 of the housing 60. In other embodiments, a mobile electronic device housing may be waterproof or water resistant and does not require a separate waterproof or water resistant housing. In such instances, the mobile electronic device may include a male or female connector adapted to receive an accessory connector 9 with a waterproof adapter 50 as disclosed herein.

FIG. 6C depicts a side view of the waterproof adapter 50. The tension tabs (54 a-d) can each include receiving notches 57 a-d (57 c and 57 d are not visible in FIG. 6C). The receiving notches 57 a-d can be configured to receive corresponding aperture protrusions (e.g. 64 a-b) located on an inner surface of the connector aperture 40 (see FIGS. 8A). When the aperture protrusions (64 a-b) engage the receiving notches (57 a-d), the engagement of the respective features can resist removal of the waterproof adapter 50 from the connector aperture 40. The engagement of the aperture protrusions (64 a-b) with the receiving notches (57 a-d) can provide the user with audible or tactile feedback confirming that installation has been successfully and fully accomplished. An exterior surface of the waterproof adapter 50 can be shaped to complement the shape of an inner surface of the connector aperture 40 to provide a suitable fit and/or a distinctive appearance signifying compatibility. Exemplary cross-sectional geometries of the waterproof adapter 50 can include cylindrical, elliptical, irregular, or polygonal (e.g. triangular, rectangular, pentagonal, hexagonal, heptagonal, octagonal, nonagonal, decagonal, etc.).

FIG. 7A shows a perspective view of an accessory connector 9 having a jack plug 10 and a jack plug gasket 11 located between a connector body 13 and the jack plug 10. The accessory connector 9 can also include a threaded feature 12 located near the jack plug gasket 11. FIG. 7B shows a perspective view of a waterproof adapter 50 secured to the threaded feature 12 of the accessory connector 9. The waterproof adapter 50 includes an exterior gasket or seal 52. In one example, the exterior gasket 52 can be an O-ring. The exterior gasket 52 may be made of a poloxamer or any other suitable polymer (e.g. thermoplastic elastomer) adhered to or overmolded onto the exterior gasket channel 51 located on an outer circumference of the body of the waterproof adapter 50. When the accessory connector 9 of FIG. 7B is installed into the connector aperture 40 of the housing 60, the exterior gasket 52 associated with the waterproof adapter 50 can form a liquid-tight seal against a corresponding gasket seating surface of the connector aperture 40.

In some embodiments, the threaded feature of the waterproof adapter 50 may instead be a bayonet-style attachment feature similar to the bayonet-style mounting feature in the connector aperture 40 depicted in FIGS. 4A-B. The bayonet-style attachment feature may also include one or more cam-receiving features similar to those depicted in FIGS. 4A-B, which correspond to one or more cam features extending radially from the accessory connector (e.g., see FIG. 3). In such embodiments, the bayonet-style attachment feature of the waterproof adapter 50 can receive a bayonet-style mounting feature of the accessory connector 9, such as that depicted in FIG. 3, thereby forming a watertight seal between the waterproof adapter 50 and the accessory connector.

FIG. 8A depicts a side cutaway view of a housing 60 surrounding a mobile electronic device 70. The mobile electronic device includes a female connector 72 adapted to receive a male connector. In one example, the female connector 72 can be a headphone jack configured to receive a jack plug 10. In another example, the female connector 72 can be a charging port, such as a LIGHTNING port or micro-USB port, configured to receive a compatible charging cable or data transfer cable.

FIG. 8B shows a side cutaway view of a mobile electronic device 70 encased in a housing 60. The housing 60 can include a connector aperture 40 configured to receive an accessory connector 9 having a waterproof adapter 50 attached thereto. The connector aperture 40 can include aperture protrusions 64 a and 64 b that extend inward toward a centerline axis of the connector aperture. A lip receiving notch 63 can be located on an inner surface of the connector aperture 40 and can be adapted to receive one or more lip portions (e.g. 54 a-d) of the waterproof adapter 50.

As shown in FIG. 8B, the waterproof adapter 50 can be secured to the accessory connector 9, and the accessory connector can be inserted into the connector aperture 40 of the housing 60. The accessory connector 9 can include a jack plug 10 extending therefrom, and the jack plug can be received by a female connector 72 located within the encased mobile electronic device 70. The accessory connector 9 can include a jack plug gasket 11 that is configured to provide a liquid-tight barrier when pressed against a gasket seat 55 (see FIG. 6B) of the waterproof adapter 50. In some embodiments, the jack plug gasket 11 may be attached to the waterproof adapter 50 (e.g. resting on, adhered to, or overmolded on the gasket seat 55, which is visible in FIG. 6B). An exterior gasket 52, which is located in an exterior gasket channel 51 of the waterproof adapter 50, can form a water-tight barrier by compressing against the inner wall of the connector aperture 40. As shown in FIG. 8B, lip portions 54 a and 54 c can extend into the housing 60 and either beyond an inner perimeter edge of the connector aperture 40 (see, e.g., the position of lip portion 54 a with respect to the inner perimeter edge of the connector aperture 40) or into a lip receiving notch 63 on the interior of the encasement (see, e.g., the position of lip portion 54 c relative to the lip receiving notch 63). In some embodiments, the housing 60 may include only a lip receiving notch 63. In certain embodiments, the lip receiving notch 63 may be located on an inner surface of the connector aperture 40.

Receiving notches (e.g. 57 c) in the waterproof adapter 50 can be configured to receive a corresponding aperture protrusion (e.g. 64 b). Physical engagement between the lip portions (e.g. 54 a-d) of the waterproof adapter 50 and the lip receiving notches (e.g. 63 b) of the adapter resists accidental removal of the accessory connector 9 and waterproof adapter 50 from the connector aperture 40. Similarly, physical engagement between the aperture protrusions (e.g. 64 a, 64 b) and the receiving notches (e.g. 57 c) of the waterproof adapter 50 resists inadvertent removal of the accessory connector 9 and waterproof adapter 50 from the connector aperture 40.

FIG. 9 shows a front view of a housing 60 for a mobile electronic device. The housing 60 can have a port 40 (i.e. connector aperture) in one of its external surfaces and a port-sealing bung 905 designed to seal the port by providing a liquid-tight seal therewith. The port-sealing bung 905 can be attached to the housing 60 by a tether 910. FIG. 10 shows a close-up top perspective view of a portion of the housing 60 of FIG. 9 showing the port 40 and port-sealing bung 905 in greater detail. The tether 910 can be a flexible portion that connects the port-sealing bung 905 permanently, semi-permanently, or removably to the housing 60. The tether 910 can be made of an elastomer, metal, fabric, or any other suitable material that can withstand exposure to liquids. In one example, the port-sealing bung 905 can have a body with a cylindrical or barrel shape. The port-sealing bung 905 can have an exterior gasket channel 951 located proximate an outer circumference of the body at or near a middle region of the body. The gasket channel 951 can be configured to receive a gasket or seal, such as an O-ring (the port-sealing bung 905 in FIG. 10 is shown prior to installation of the gasket or seal). The bottom end of the port-sealing bung 905 can include a perimeter, and the perimeter can include one, two, three, four, or more tension tabs (953 a-d) extending therefrom. In one example shown in FIG. 10, the perimeter can include four tension tabs (953 a-d) extending therefrom. Each tension tab (953 a-d) can have a lip portion (e.g. 954 b, 954 d) extending outward radially (e.g. flaring outward) from the tension tab (i.e. extending outwardly from a centerline axis if the port-sealing bung). In other embodiments, the number of tension tabs may be two, three, five, six or more. The lip portions (954 a-d) can project outwardly at a predefined angle from the tension tabs (953 a-d) and can be configured such that the port-sealing bung 905 can be removably installed into the port 40 of the housing 60. In one example shown in FIG. 10, the lip portions (954 a-d) can project outwardly from their respective tension tabs (953 a-d) at an angle of about 45 degrees relative to a centerline axis 100 of the port-sealing bung 905. Depending on considerations relating to ease of insertion, ease of removal, and protection against inadvertent removal, the lip portions (954 a-d) can project outwardly from the tension tabs (953 a-d) at other suitable angles, such as about 1-15, 15-30, 1-60, 15-60, 15-45, or 30-45 degrees, relative to the centerline axis of the port sealing bung 905.

To ensure that water is unable to reach the mobile electronic device and cause damage to the mobile electronic device, it can be desirable for the port-sealing bung 905 to be firmly installed in the connector aperture 40. In one example, the port-sealing bung 905 may require a tool to uninstall the port-sealing bung 905 from the port 40. In one example, an extraction force of at least 15 newtons may need to be applied to the port-sealing bung 905 to uninstall the port-sealing bung from the port 40, where the extraction force is measured as a vector aligned with the centerline axis of the body of the port-sealing bung and directed away from the port 40. In another instance, an extraction force of at least 20 newtons may need to be applied to the port-sealing bung 905 to uninstall the port-sealing bung from the port 40, where the extraction force is measured as a vector aligned with the centerline axis of the body of the port-sealing bung and directed away from the port 40.

As shown in FIG. 9, the housing 60 can have a port (i.e. connector aperture) located in one of its external surfaces and a hinged door 920 designed to seal the port by providing a liquid-tight seal therewith. FIG. 9 shows the hinged door 920 in an opened position, exposing a sealing material disposed on an inner surface of the hinged door. The sealing material disposed on the hinged door 920 is represented by shading in FIG. 9. The hinged door 920 can provide access to an electrical connection, such as a charging port or data port of the mobile electronic device. The hinged door 920 can be attached to the housing 60 by any suitable hinged mechanism. To ensure that water is unable to reach the mobile electronic device and cause damage to the mobile electronic device, it can be desirable for the hinged door 920 to be firmly installed over the port when in the hinged door is in a closed position. In some examples, a tool may be required to open the hinged door 920 to expose the port in the housing 60. In one instance, an extraction force of at least 15 newtons may need to be applied to the hinged door 920 to expose the port in the housing 60, where the extraction force is measured as a vector aligned with a centerline axis of the port and directed away from the port. In another instance, an extraction force of at least 20 newtons may need to be applied to the hinged door 920 to expose the port in the housing 60, where the extraction force is measured as a vector aligned with a centerline axis of the port and directed away from the port. The necessary extraction force can be controlled by the magnitude of the interference fit between a locking feature of the hinged door 920 and a receiving feature located on the housing 60, where the locking feature of the hinged door is designed to produce an interference fit with the receiving feature when the hinged door is in a closed position. In some instances, the hinged door 920 may be removable from the housing 60 to permit replacement of the hinged door with a replacement hinged door that is easier or more difficult to transition from a closed position to an opened position to allow the housing to be modified to suit an intended use. For example, if the housing 60 will be used by an employee at a waterpark where the housing is frequently exposed to water and potential drops, the risk of water damage to the mobile electronic device is relatively high, so it can be desirable to install a hinged door 920 that is more difficult to open to reduce the risk of the hinged door inadvertently opening during use in a wet environment.

An accessory connector 9 for an accessory device can be configured to provide a liquid-tight seal when inserted into a connector aperture 40 of a waterproof housing 60 for a mobile electronic device. The accessory connector 9 can include a male connector 30 extending from a body 13 of the accessory connector.

The waterproof adapter 50 can include an interior gasket seat 55 proximate the interior surface of the body. The waterproof adapter can include a first attachment feature on the interior surface of the body 59. The first attachment feature can be configured to attach to a second attachment feature on an accessory connector of an accessory device to form a liquid-tight seal between a jack plug gasket on the accessory connector and the interior gasket seat of the body. In one example, the attachment feature on the interior surface of the waterproof adapter 50 can be a threaded feature 56. In another example, the attachment feature on the interior surface of the waterproof adapter 50 can include two or more bayonet-style mounting features. Each tension tab (e.g. 53 a, 53 b) of the waterproof adapter 50 can include a receiving notch (e.g. 57 a, 57 b) proximate each lip portion (e.g. 54 a, 54 b), as shown in FIG. 6C. Each receiving notch (e.g. 57 a, 57 b) can be configured to receive an aperture protrusion (e.g. 64 a, 64 b) extending from an inner surface of a connector aperture 40 of the waterproof housing 60 for the mobile electronic device 70. Each lip portion (e.g.54 c) can be configured to associate with a lip receiving notch (e.g. 63) in a connection aperture 40 of the waterproof housing 60, as shown in FIG. 8B. In some examples, the exterior gasket 52 disposed within the exterior gasket channel 51 on the exterior surface of the body 59 of the waterproof adapter can be an O-ring.

A waterproof case for a mobile electronic device 70 can include a housing 60 that is adapted to cover at least a portion of the mobile electronic device. The mobile electronic device 70 can include an electrical or optical connector (e.g. 72) that is accessible proximate an external surface of the mobile electronic device. The waterproof case can include a connector aperture 40 extending through the housing 60. The connector aperture 40 can provide access to the mobile electronic device 70 encased in the housing 60. The connector aperture 40 can be located proximate the electrical or optical connector (e.g. 72) of the mobile electronic device 70 when the mobile electronic device is installed in the housing 60. A port-sealing bung 905 can be attached to the housing 60 by a tether 910, as shown in FIG. 10. The port-sealing bung 905 can be adapted to fit within the connector aperture 40 to provide a liquid-tight seal therewith. The port-sealing bung 905 can have a body having an exterior surface and two or more tension tabs (e.g. 953 a, 953 b) extending from a first end of the body. Each tension tab can include a lip portion (e.g. 954 a, 954 b) extending outwardly relative to a centerline axis of the body. The port-sealing bung 905 can include an exterior gasket channel 951 proximate the exterior surface of the body. The exterior gasket channel 951 can circumscribe the exterior surface of the body. An exterior gasket can be disposed at least partially within the exterior gasket channel 951 on the exterior surface of the body. The exterior gasket can be adapted to form a liquid-tight seal between the port-sealing bung 905 and an inner surface of the connector aperture 40 when the port-sealing bung is inserted into the connector aperture. Each tension tab can include a receiving notch configured to receive an aperture protrusion extending from the inner surface of the connector aperture 40 of the waterproof housing 60 when the port-sealing bung is installed in the connector aperture. The connector aperture 40 can include two or more lip receiving notches, and each lip receiving notch can be adapted to receive one or more of the lip portions of the port-sealing bung 905 when the port-sealing bung is inserted into the connector aperture 40. In some instances, a tool may be required to remove the port-sealing bung 905 from the connector aperture to avoid inadvertently uninstalling the port-sealing bung from the connector aperture during use of the waterproof case. Ensuring that the port-sealing bung 905 does not inadvertently come free of the connector aperture 40 during use is very important in certain applications, such as when using the protective case in the presence of flammable or explosive fumes or gases, such as on an offshore oil platform. In such an application, it can be critical for the case to completely contain any sparks that may occur within the electronic device as a result of static electricity or from ordinary operation. To ensure containment of any sparks within the electronic device, it is essential that the port-sealing bung 905 remain firmly in place within the connector aperture 40 during use. In some examples, when the port-sealing bung 905 is installed in the connector aperture 40, an extraction force of at least 15 newtons may need to be applied to the port-sealing bung to uninstall the port-sealing bung from the connector aperture, where the extraction force is aligned with the centerline axis 100 of the body of the port-sealing bung.
